RESEARCH OF THE DIESEL ENGINE FAILURE DEPENDENCY ON ENGINE OPERATING CONDITIONS
the paper deals with the analysis of the factors and aspects covered by the Diesel Engine Reliability Theory and relevant for the discussion of engine reliability. The paper suggests and examines indicators for the assessment of engine reliability, and quantitative function for the evaluation of engine technical condition. The integrated effect of mountainous dessert on automotive engines is also examined although it has received little research attention so far, whereas findings of quantitative criteria analysis intended for reliability assessment under difficult conditions have not been publicly reported as they have been accomplished by manufacturers of military vehicles.
Engine operating conditions refer to the manner of engine use, intensity of engine operation, different types of engine loads and their sequence, as well as culture and qualification of drivers, servicemen and maintenance personnel, provision of repair and diagnostics equipment, etc.
Research of the case under consideration has been accomplished in mountainous desert of Afghanistan showing complicated climatic conditions. For the purpose of collecting precise and accurate data, vehicles used by the Provincial Reconstruction Team situated in Ghor province (Afghanistan) were selected for the research. Their operation course, failures, and repairs can be tracked and captured more precisely than those of civilians as their data are recorded in data logs.
